How to create an application for iOs yourself: step-by-step instruction

Today, the IT sphere is developing quite fast. Each person, if he wants to try himself in it, chooses one of the directions and moves to the goal. Many people prefer developing mobile applications for iOS and Android. To create them, of course, is quite difficult, patience, knowledge and free time are needed. If you are serious about this, you should learn and go to the goal. How do I create an iOS app on my own?

Development environment

First, you need to install the program, where you will work with the interface and prescribe the actions for the necessary elements. The most common is Xcode. Unfortunately, this development environment is available only to users of Apple products. At the moment there is no official version for Windows or Linux. A different version of this program is required for a different version of iOS.

Add-ons for working with graphics

To develop an image or design for games, you need to install a utility for working with graphics. A common application is CorelDraw, which allows you to create photos using vector graphics. Of course, for a full-fledged work you need to purchase the full version, but standard methods can be used for free.

Objective-C

The Objective-C programming language is used to create a functional for the game. As you can see, it went from the C language family, so if you've studied a different programming language before, you can spend enough time on in-depth study and start creating your applications. Of course, there are many books on the study of Objective-C.

Create an account

To subsequently sell your application, you need to register with the AppStore. In it, you can also provide other users with open access so they can test the program. Of course, it is not free. You will need 100 dollars to put your application for sale for one year.

Also in the App Store you can see the test applications. Some are provided with information on how they were developed. Look at similar examples with what you want to create and try to do something similar.

Scheduling an application

First you need to determine the target audience for your application. From this will depend on the interface and functionality. Of course, if you are developing a program, then it is worthwhile to achieve a solution that was not there before. This is the only way to achieve popularity.

Also it is necessary to decide how the application will be arranged. You should make the interface as simple as possible so that it attracts new people, and does not frighten you without showing your capabilities.

Each button should display its actions and show what it will do. The user should not have questions about what any key will do. Think over, and then implement, a quality interface.

Creating an Application

First, you need to open the development environment and create a new project. To do this, go to the "File" section and go to "Application". Next, select "iOS" and go to the empty application "Empty Application".

You can create an application for iOS using various templates that are created for different tasks. For a start, it's better to use an empty one to deal with all the subtleties. In the future you can apply them.

In the new window, enter the product name and your ID, also specify the class prefix. If you are a novice developer, you should specify in the field of the identifier "com.example", and in the prefix field "XYZ". Next, choose from the proposed devices "iPhone" and confirm their actions.

Use Storyboard

At the beginning of the path to create an application for iOS, you can use Storyboard. What it is? This is a function that allows you to visually present all your screens in the program. It shows all the windows and transitions that are used between them. This is a good helper in creating a program. To open Storyboard you need:

• Go to the "File" and "New";

• Select the "File" button and go to "User Interface";

• Then select the desired function;

• It only remains to select the device "iPhone" and name the file.

You should remember that you need to save it to the folder where the data about your project is stored.

Add a screen

To add a screen, you must use a view controller. It allows you to determine how the interface looks to the user. There are many built-in view controllers. You can see each available option and decide which design you like best.

· To do this, go to the "Main.storyboard" file through the navigation.

· Select "Object Library" to load all the necessary objects.

· You need to click on "View Controller" and drag it to your project. So you will add your first screen.

Objects

How do I create a mobile app for iOS? So, you have defined the interface and added a screen, now you can proceed to create certain objects. To use standard items, open the Objects Library list. If you find a suitable object, then you can transfer it to your screen. It can be easily moved and scaled.

Editing items

By placing objects, you apply a kind of constructor. You can create an application for iOS and so, but these elements have an ugly, standard look. To change the design: color, font, add pictures and other parameters, you need to select an object and go to its properties. You can do this by clicking on the button "Attributes Inspector" (the label resembles a shield).

Navigation pane

Soon you will add a lot of other screens, and the program will require you to enter the navigation so that you can easily find the information you need. To add it, you need to:

• Find the place where this element will be located. It is better to apply it to the initial screen to control other windows.

• Press the "Editor" button and go to the "Embed In".

• It remains only to select the necessary element - "Navigation Controller".

Additional Features

As you can see, we have not yet used the programming language to create an application for iOS. This moment will only be on you. You need to figure out what your application should do and sip the objective-C for that. If you do not have a good programming skill, you should read additional literature.

Testing the application

Xcode has an emulator that allows you to test. After creating an application for iOS, it needs to be tested and tested. To do this, go to the "Simulator and Debug" section. Select the device you want to test with.

Build the program

How do I create an iOS app on my own? To fully test the program or game, you need to assemble the project. Go to the "Build" item and click on it. So you compile the application, and after that it will start immediately. It will take you about five minutes. You will be able to observe how the assembly will occur.

Verification device

To finally make sure that your project is working, you need to perform testing on your device. If you have an iPhone, then you can do it without problems. Connect your device to the PC. Then we carry out the actions that we have already considered. Click on the button "Device and Debug", and then go to the item "Build". After a few minutes, when the application is ready, it will start on your device.

If you understand how to create an application for Android and iOS, but you have some problems, you need to fix them. You can see in the console what errors occurred during the testing. In general, this is a rather important process, because if you test your application well, it will bring success. Also you can take the help of your friends. To do this, send them your application and wait until they find errors.

Publication of the project

You need to create an assembly. To do this, select the "Distribution" item in the menu and click on the "Build" button. Next, select your project and archive it. You should understand that the application should be optimized for the necessary platform and be suitable for the retina display, without it, it will not be approved.

Go to the account in the AppStore and add a new program or game. You will need to enter all information about the application: title, description, keywords, category, copyrights and contacts. We also fill in the field with the price and the rights. It only remains to add an icon to your application and a few screenshots.

Checking

After downloading your application it will be checked. In a few days you should be given an answer. At the initial stage the program is automatically checked. If everything went well, then it is transferred to the "In review" state. If this does not happen, in a few hours you will be able to receive an answer to the mail. Also you can get information about how you can fix defects and what you need for this.

If the application has passed all the checks, it will be placed in the Apple Store for sale. Your task now is to advertise the program or the game. This will determine how much money you will earn. You can use various services for advertising.

Conclusion

Application development is done in a similar way, but in a different development environment for Windows. How do I create an iOS app? This is a rather long and complex process. This must be approached with certain knowledge and skills. Only so you can achieve something. You can realize your ideas and without certain skills. Choose the right company and consider how much it costs to create an application for iOS. You can also order some components if you can not do something yourself.
